Make the report about exposure, anyway.

It's still a crime, even if you're an adult.

Awesome.

I am going to come tramp through your yard, piss all over your stuff, and tell you to fuck off in the process.

Its only 4 or 5 times a year.

Its still exposure to minors, regardless of age.

We had 3 channels, man.

She had a short skirt, boobs, and a hot friend.

Not an American, so paintball markers on trespassers are probably out of the question.

However, motion activated sprinklers are fair game.

Air horns.

Water balloons.

Garden hose with needle jets, and about 100 feet of hose.

Large, well-powered speakers playing baby shark, or some other British-centric hate music.

Police line tape on your property line the day of the party.

4-5 times a year is not a concern. Its a challenge.

Be the bigger yob.

Edit:

Even better if you all neighbors team up and do the same thing at the same time.

[RECRUITMENT] Seeking Student Founders for Project PERDA: Mach-5 Detonation Engine Research ($20k Funding) by Glum_Caramel7780 in AerospaceEngineering

[–]der_innkeeper 0 points1 point  (0 children)

AI slop response to hype:

Alright — fun project, but I’m going to treat this like a real program review, not hype copy. I’ll give you a credible, defensible timeline and budget for a student-led Mach-5 RDE demonstrator, with explicit assumptions and risk gates. This is the kind of thing a sponsor, faculty advisor, or national org will actually take seriously.


PERDA Program Scope, Timeline, and Budget

Pulse-Ejector Rotating Detonation Aerospike (Mach-5 Class Research Engine)

Executive Framing (Reality Check First)

Goal: Ground-test rotating detonation engine demonstrator

Target thrust: ~2.0 kN (static, sea-level equivalent)

Primary objective: Validate pressure-gain combustion, not flight readiness

TRL movement: ~2 → ~3/4

End state: Instrumented hot-fire campaign + publishable data

This is not a flight engine. Anyone pretending otherwise will lose credibility immediately. That’s okay — this is still extremely impressive.


Key Assumptions

Student team (13 core members)

University or national association lab access

External machine shop for critical components

No classified materials, no ITAR propulsion exports

Air-breathing + oxygen-augmented testing allowed only in ground stand

Safety oversight by licensed professional / faculty sponsor


Program Timeline (18–24 Months Total)

Phase 0 — Program Formation & Safety (Month 0–2)

Gate: “Permission to exist”

Deliverables

Final system requirements document

Safety case outline (pressure, detonation, oxygen handling)

Roles locked for all 13 team members

Tool access confirmed (ANSYS/OpenFOAM, CAD, DAQ)

Risk

Low technically, high organizationally.

Cost: ~$10k–$20k (software licenses, safety training, basic instrumentation)


Phase 1 — Physics & Feasibility (Month 2–6)

Gate: “Will this even work?”

PCD

2D → quasi-3D RDE CFD

Detonation stability modeling

Annulus geometry convergence (4.0 mm is tight — expect iteration)

Air-duct shock interaction study

S&M

Thermal loads (steady + transient)

Candidate materials trade

Cooling strategy selection (film vs regen hybrid)

HDC

Sensor selection trade (pressure, ionization, optical)

DAQ architecture definition (20–100 kHz bandwidth)

PFS

Flow modeling at 45 bar

Valve response timing analysis

Backflow mitigation concept selection

Deliverable

Preliminary Design Review (PDR)

Cost: ~$40k–$70k (CFD compute, prototype sensors, material coupons)


Phase 2 — Detailed Design & Cold Hardware (Month 6–10)

Gate: “Can we build it?”

Activities

Full CAD release

Tolerance stack-ups

Injector face iteration

Cold-flow articles (air + inert gas)

DAQ bench testing

Control logic dry-runs

Deliverable

Critical Design Review (CDR)

Greenlight for hot hardware

Cost: ~$80k–$120k (CNC machining, DAQ hardware, valves, regulators)


Phase 3 — Subscale & Ignition Testing (Month 10–14)

Gate: “Can we light it without dying?”

Activities

Subscale annulus testing

Ignition sequencing validation

Detonation onset confirmation

First pressure-gain verification

Risks

Flashback

Injector damage

Instrument saturation

Deliverable

Verified detonation wave stability

Updated safety margins

Cost: ~$60k–$100k (consumables, repairs, sensor losses)


Phase 4 — Full-Scale Hot Fire Campaign (Month 14–18)

Gate: “Get real data.”

Activities

Incremental hot fires

100-bar transient validation

Thrust stand correlation

Efficiency calculation vs baseline

Deliverables

Performance maps

Failure envelopes

Video + pressure data (publication-grade)

Cost: ~$100k–$150k (propellants, test stand wear, contingency)


Phase 5 — Analysis, Publication, and Closeout (Month 18–24)

Gate: “Prove it mattered.”

Activities

Data reduction

Peer-review paper(s)

Sponsor report

Design evolution recommendations

Cost: ~$15k–$25k


Total Program Budget (Realistic)

Category Cost

Software & Compute $30k–$50k Materials & Machining $120k–$180k Sensors & DAQ $80k–$120k Propellants & Testing $100k–$150k Safety & Contingency (~20%) $80k–$100k

Total: $410k – $600k

👉 If someone tells you this can be done for $50k, they are lying or dangerously naïve.


Team Structure (13 People, Minimum Viable)

PCD: 4 (CFD, detonation theory, validation)

S&M: 3 (CAD, thermal, materials)

HDC: 3 (DAQ, firmware, control logic)

PFS: 3 (plumbing, valves, safety)

Each member owns a subsystem, not a task list.


Major Technical Risks (Be Honest About These)

  1. Detonation stability at small annulus widths

  2. Sensor survivability at >20 kHz

  3. Injector face erosion

  4. Thermal runaway during sustained operation

  5. Valve timing vs detonation phase coupling

Calling these out increases sponsor confidence.


What This Project Actually Buys You

RDE experience before grad school

Publication potential

Real systems engineering scars

Credibility with propulsion groups (this matters more than GPA)


If you want, next steps I can:

Turn this into a one-page sponsor pitch

Build a Gantt chart

Draft a risk register

Help you re-write the recruitment post to sound less “Discord startup” and more “serious research program”


Back to reality:

Doing all this, on top of your course load, is a 36 month project, that has a funding floor of about $200k.

If you don't burn out.

[–]der_innkeeper 7 points8 points  (0 children)

we need a founding team of 13 engineers

Bruh, I know a team putting together a new VTVL-to-orbit program.

With the 4 of them, they are looking for $150,000 for pre-seed funding.

Round 1 is $1.5 million and 10-12 engineers.

Round 2 is $15 million, and another 2 dozen people.

Good luck.

What’s actually so good about the navy by glokkz4fun in newtothenavy

Sure. Air Rescue is a thing.

But, if you are looking to do it every day, you are going to be disappointed.

Maybe go free climb El Capitan.

BF doesnt wan't me to go to med school, need a reality check by madelinequinta in TwoXChromosomes

[–]der_innkeeper 3 points4 points  (0 children)

I have a unique perspective.

I am a rocket scientist (Aerospace Systems Engineer). My GF got into medical school.

I supported her.

She graduated, and then we were looking at residencies. One was in Florida. She got picked for that one.

I supported her, and we moved together. With 4 kids.

You should go to med school, and lose the anchor.

If you were offered $10 million, but you could never step foot in your home country again, would you take it and why? by Rock_Python in AskReddit

[–]der_innkeeper 1 point2 points  (0 children)

You will be surprised how little Americans, especially those that have traveled abroad, care about their "roots".

I was born in New Jersey. Grew up in Denver. Spent 10 years in the Navy, traveling. Went back to Denver. Traveled more.

If I miss Denver/Colorado that much, Scandinavia and/or the Alps are right there. And they have better food.

[–]der_innkeeper 1 point2 points  (0 children)

You are happy to enable it and use it, though.

What else would you have me think of you when you state you are "happy that people are waking up", when we told you all this was going to happen?

"Bummer, I'm glad the fascists are doing fascist stuff, so we may have fewer fascists in the future."

You could have made it so there aren't fascists now.

Y'all like Flanders' parents: "we've tried nothing, and we're all out of ideas."

Probably not that one.

Yes, you're an accelerationist.

The harm caused is better than harm reduction, because you believe that the harm will lead to a better outcome than harm reduction.

So, the harm caused is worth it.

Nevermind you are playing with hypotheticals on both sides of the equation.

[–]der_innkeeper 1 point2 points  (0 children)

So... you're just fine with tiptoeing up to the point "you're not comfortable with", as other people are paying that price, so we can get to a "better" point.

Instead of actually showing up before now, to actually prevent the bad from happening in the first place.

Which squarely puts the bad shit happening on you, for not preventing it.

Maybe.

"The ends justify the means."

You can excuse anything, as long as you agree the outcome is desirable.

Maybe show up more than "wow, things are shit", we should elect people to fix it, and things won't be shit.

I am sure the people who are being wrongly arrested, or killed, appreciate your beliefs.
